Web License error in Linux

while specifying the web license in Linux an error is being encountered i.e., Web:SSL handshake failed. How to rectify this error

Hello @Vijaybhvs,
I would check the Web License FAQ page on Itasca’s website - https://www.itascainternational.com/software/faqs/how-can-i-resolve-software-license-related-errors
Ensure your firewall is open on port 443.

Hello @Vijaybhvs @dblanksma , Did that solution work for you? I’m having similar issues on Windows with the web license, port is open and app is allowed through the firewall

No still I am facing the same problem in Linux

Hi, it seems that the reason for this is an old qt-library not prepared to work with a modern openssl:
qt.network.ssl: QSslSocket: cannot resolve EVP_PKEY_base_id
qt.network.ssl: QSslSocket: cannot resolve SSL_get_peer_certificate
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_get_peer_certificate

In the latest Itasca-Update (v9.181) the problem is solved. However, we have also older codes (3DEC v7, FLAC3D v7), which unfortunately even with the latest update are still linked with old qt-library.
It need to me mentioned also, that the qt5 is actually since 2023 no longer supported. It would be a good step forward, to migrate to qt6.
@ItascaTeam: when a working linux-update for V700 is to be expected? Is the migration from QT5 to QT6 already planed?

Hi Sven,

The migration to Qt6 is already complete. It is available in our updates versioned as 9.0 and later. The most recent drop was version 9.5. The port to Qt6 is a much bigger effort than a re-link with the newer versions of Qt, and we don’t plan to update versions 700 and older to Qt6.

Hi, thank for you answer. I understand the difficulty to port the old Itasca-Software (e.g. 7.0) to newest QT, however there is already a Linux-Version for V9.0 with QT5 working with the web-license. Unfortunately, the newest Linux-Version for V7.0 (update from the 27th of October 2025) is still not able to build secure connection with the web-license-server, thus in our case it is not possible to use the software under Linux at all…
